Shrub rose plant named ‘JACmorde’

ABSTRACT

Shrub rose plant characterized by its deep pink blooms presented in clusters; ease of propagation by hardwood or softwood cuttings; compact, well-branched habit; resistance to common fungal diseases, and hardiness to Zone 4.

Genus and species: Rosa hybrida.

Variety denomination: ‘JACmorde’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a shrub rose plant named ‘JACmorde’ which was originated by me by crossing the variety ‘Morden Blush’ (U.S. Plant Pat. No. 8,054), with an unnamed red floribunda seedling (not patented) (‘JACient’ (U.S. Plant Pat. No.6725)×‘KORholst’ (U.S. Plant Pat. No. 6117)).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having the compact habit, cold hardiness, disease resistance of the female parent combined with the large flower, glossy foliage and big flower clusters of the male parent.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

-   -   1. Deep pink blooms presented in clusters.     -   2. Ease of propagation by hardwood or softwood cuttings.     -   3. Compact, well-branched habit.     -   4. Resistance to common fungal diseases.     -   5. Hardy to Zone 4.

Asexual reproduction of this new variety by cuttings, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison With Parents

Compared to the female parent ‘JACmorde’ has larger flowers, dark versus light pink flower color and fewer petals. Compared to the male parent, ‘JACmorde’ has dark pink versus red blooms and greater resistance to blackspot and rust.

Comparison With Similar Variety

The closest variety to ‘JACmorde’ is ‘PRObril’ (Brilliant Pink Iceberg) (PP12,645). ‘JACmorde’ is more compact, has greater resistance to powdery mildew and black spot and has fewer petals.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with the Royal Horticultural Society (London) Colour Chart© 2001, except where ordinary dictionary significance of color is indicated.
